  【內(nèi)容簡(jiǎn)介】  東非大裂谷自紅海至贊比西河口,連綿三千里,從太空都能看到。這里是多姿多彩的地方,有噴發(fā)的火山、覆蓋著森林的高山、美麗的峽谷、廣袤的草原、巨大的平湖和河流,是鱷魚(yú)、河馬、獅子、大象、火烈鳥(niǎo)和非洲人的家園。BBC采用最新的高清攝影技術(shù),探討了形式東非大裂谷的地質(zhì)力量,展現(xiàn)世界上野生動(dòng)物品種最多的地貌?! isible from space, Africa's Great Rift Valley runs three thousand miles from the Red Sea to the mouth of the Zambezi. It's a diverse terrain of erupting volcanoes, forest-clad mountains, spectacular valleys, rolling grasslands, huge lakes and mighty rivers, and is home to crocodiles, hippos, lions, elephants, flocks of flamingos and a diversity of indigenous peoples.  Using state-of-the-art high definition filming techniques, this series investigates the geological forces which shaped East Africa's Great Rift, and which make it one of the world's most wildlife-rich landscapes.  Part 1: Fire  The valley is the product of deep-seated geological forces which have spewed out a line of cloud-wreathed volcanoes stretching from Ethiopia to Tanzania. Their peaks provide a refuge for East Africa's most extraordinary wildlife, including newly discovered and previously unfilmed species which have evolved surprising survival strategies to cope with their challenging mountain environment.  Part 2: Water  The Great Rift Valley channels a huge diversity of waterways - rivers, lakes, waterfalls, caustic springs and coral seas - spanning from Egypt to Mozambique. Some lake and ocean deeps harbour previously unseen life-forms, while caustic waters challenge life to the extreme. But where volcanic minerals enrich the Great Rift's waterways, they provide the most spectacular concentrations of birds, mammals and fish in all Africa.  Part 3: Grass  The Great Rift Valley provides the stage for an epic battle between trees and grass - its course influenced by volcanic eruptions, landscape and rainfall. On its outcome rests the fate of Africa's great game herds. In the Rift's savannas, grazers and their predators struggle to outwit each other, forcing one group of primates to develop a social system that paved the way for the evolution of mankind.
